Can't answer all questions, we have had the pair since mid November 2017, the previous owner gave them to us because he said the male became too snappy, don't know exact age but by the size of them they are adults. Feeding medium size rats (frozen). My record of feeds shows 1X rat19 & 21 Nov, 1X rat 7 & 25 Dec, 1X rat 3 & 22 Jan and 2X mice & 1X rat 10 Feb. The cage is inside so pass at all times & we do have a dog that likes to look at them. Does this help
